Description

when i install the npcap driver everything seems to be working fine, but as soon as i reboot my pc the driver is stopped and cant be started because the system cannot find the specified file.
wireshark gives this error:
The capture session could not be initiated on interface '\Device\NPF_Loopback' (Error opening adapter: Er is een niet-bestaand apparaat opgegeven. (433)).

when i try to start with cmd i get this:
C:\Windows\system32>net start npcap
Systeemfout 2.

Het systeem kan het opgegeven bestand niet vinden.

Research direction

Start by reviewing the attached DiagReport-20191022-174200.txt and reproducing the reboot followed by net start npcap. Compare the service and driver state before and after reboot, using the Wireshark NPF_Loopback failure as the check. Done means the npcap service starts after reboot and captures from the loopback interface.
